Abstract

In this paper, we demonstrate a novel 20-GSample/s burst-mode clock and data recovery (BM-CDR) technique for optical multiaccess networks. The BM-CDR incorporates an injection-locking method for clock recovery and a clock phase aligner employing space sampling with two multiphase clocks at 10 GHz and a phase-picking algorithm for automatic clock phase acquisition. The design provides low latency and fast response without requiring a reset signal from the network layer. The BM-CDR achieves a bit error rate <\ 10 -10 while featuring instantaneous (0-bit) phase acquisition for any phase step (\pm 2\pi\ \hbox{rad}) between successive bursts. We also compare the data with probabilistic theoretical predictions to validate the experimental results.
